The Past And Future Of Contact Lenses

by: Mary Williams

Have you ever wondered about the history of contact lens? How have they been invented? And how do contacts correct vision?

Your vision depends on light beams hitting the retina (the back of your eyeball) at the same point. When the light does not meet at the same point, vision becomes blurred.

To correct this vision problem a lens needs to be placed in front of the eye to compensate. The lens then becomes a 'perfect' eye and light beams converge together at the retina.

Even though eye glasses have long provided the needed correction for vision problems, contact lenses were a marvel of science allowing individuals the freedom to forgo the hassle of slipping, fogging and distracting eye glasses. The inside surface of the contact lens is fitted to the shape of your eye so it stays in place. The outer surface is shaped to the corrected curve (as in eye glasses).

Originally, these contacts were made of hard plastic that required saline solution drops on a regular basis to keep moist. They were also prone to 'popping' out and causing discomfort when blinking. Newer contacts are made from a soft plastic that allows the eye to 'breathe'. They are much more comfortable to wear and because of the high water content of the material they require less maintenance during use. Soft contacts cling to the layer of tears covering the cornea and move slightly with each blink. This ensures that the eye stays moist and foreign materials can be safely washed out.

Basically, the purposes of contact lenses are to correct common vision problems like short-sightedness (myopia - when a person can focus on objects close to them but not far away) and far-sightedness (hyperopia - where the individual can see well at a distance but has trouble focusing clearly on print and other close objects). Now even individuals with astigmatism (where the shape of the cornea is elongated) or presbyopia (an age related condition that used to require bi-focals) can find contact lenses to suit their unique needs.

Currently, contacts are now developed in a disposable variety that means no cleaning is required. There are also contacts that can be worn for a week or even a month without being removed and cleaned - great for those who hate the daily hassle.

Many contact lens wearers are experimenting with changing the color of their eyes. While older versions produced harsh colors, new versions of color contacts (which can even be worn by individuals who have no vision problems) can be found in subtle shades and can even change dark eyes to light.

The contacts will be improved in the future. There is even talk of contacts created to prevent conditions like myopia from developing in children. Whatever happens, those with vision problems can count on new solutions being added to the currently available options all the time.

Disposable Contact Lenses ? Simple But Powerful

by: Martin Smith

Throughout time there have been various means of correcting vision. There was the monocle, then the glasses that were on a chain or a stick, and then there were eyeglasses as we know them today but there were not as many styles as there are now. As technology improved the lenses of glasses were getting smaller. Since many people were always losing or breaking their eyeglasses they were hoping for a way to wear glasses and not have to worry about them being lost or breaking them.

Contact lenses came along and they were great but expensive. If you lost them or dropped them you would have to get new ones. I knew of someone who lost one of her contact lens and she had developed an infection in her eye. The doctor examined her only to find the contact lens had slipped and was not in the proper place. Traditional contact lenses were rigid and took some getting used to.

Unsure About LASIK? Alternatives to LASIK Surgery

by: Nicola Kennedy

It?s true that LASIK is one of the most prevalent types of eye surgery. However, a few people are either not comfortable with, or not suitable for LASIK surgery due to inadequate thickness of the corneal tissue. There are several alternatives to LASIK surgery, each possessing certain characteristics that make it more appropriate in a particular situation. The procedures may be different, but the key intent is to correct the vision. The following are a few of the major alternatives to LASIK surgery.

LASEK (Laser-Assisted Sub-Epithelial Keratomiluesis) is a recent addition to the refractive surgery catalog. As noted above, the density of the corneal tissue is inadequate in some patients, and hence, LASIK is not a possible option for them. In such a scenario, procedures like LASEK or PRK (Photo-Refractive Keratectomy) can be viable alternatives. These procedures produce the same...

FDA Approves Lasik Eye Surgery

FDA Approves Lasik Eye Surgery

by: Ron King

The Food and Drug Administration (FDA) approved a new custom lasik procedure in September of 2005. This new procedure can now treat many patients who were previously ineligible for the surgery.

Nearsightedness

Nearsightedness occurs when the eye is too long and light rays focus in front of the retina, instead of focusing on the retina. Some of the symptoms of nearsightedness are blurred distant vision, eyestrain, and squinting, along with having a difficult time seeing at night.

Although nearsightedness can be easily fixed with glasses or contact lenses (when not too severe), many people don't like to hassle with either one. With this new lasik procedure, folks will now be able to have pure vision.

Astigmatism

Astigmatism is the effect of the eye being shaped like a football, instead of round like a baseball. This deformity -- where the light rays focus on two points on the...

Whack 'em Back: Pruning Plants For More Flowers

by: Doug Green

Plants such as fuchsia and geraniums can be pruned back the end of Februray to early March. The long lanky growth of winter?s low sunlight should be pruned back hard. This stringy growth is not strong enough to support the weight of profuse summer blossoms and unless the plant is cut back, this summer the plant will look ugly when it should be a showpiece in your garden. I used to simply whack...
